In what’s being billed as “Monday Mayhem” at Rio 2016, Canada will try to clinch a spot in the quarterfinals of the men’s volleyball tournament.

The top four teams in each group advance to the knockout stage. Italy comfortably leads Pool A with 12 points while Mexico, currently with no points after four games played, is in last. It’s everything in between where things get interesting.

France, Canada, Brazil and the United States all entered the final day of the preliminary round with six points. The US defeated Mexico 3-0 on Monday, guaranteeing the squad a quarterfinal spot. Later in the day Italy will face Canada and Brazil will battle France to wrap up group play.

Three points are awarded for 3-0 and 3-1 wins, two points for a 3-2 win, one point for a 2-3 loss and zero points for 0-3 and 1-3 loses. Canada would advance to the quarterfinals with a three-point win. Anything less than three points could result in a tie-break, which is settled by matches won, match points and then set ratio.

Canada, ranked 12th in the FIVB men’s world rankings, has performed fairly well in an extremely tough pool. The Canadians started the tournament with a 3-0 upset win over the No. 5 ranked United States and then took top-ranked Brazil to four sets. After losing to 11th-ranked France, Canada defeated Mexico in straight sets.

Here’s a breakdown of how tough the competition is in Pool A.
